Which area has the most diverse diamond sources?

• A. Africa is home to the world's most diverse diamond sources.
• B. Asia is home to the world's most diverse diamond sources.
• C. Europe is home to the world's most diverse diamond sources.
• D. Americas has the most diverse diamond sources.

Answer: (A)

Geographic distribution and variety of diamond sources is being tested here. Africa stands out because it spans a wide range of diamond-bearing environments and many countries, giving a rich mix of deposit types. You can find primary kimberlite sources in several southern and central African nations, where diamonds come from deep, ancient volcanic pipes. At the same time, Africa hosts extensive alluvial deposits carried and sorted by rivers and along coastlines, as well as marine deposits in some coastal areas. This combination of multiple deposit types—kimberlite pipes, alluvial, and marine sources—across a broad geographic area and across many countries yields a level of diversity in diamond origins that is not matched elsewhere. While other continents have significant diamond production, the breadth of African sources in terms of both geology and geography explains why it’s considered the most diverse.
